Diamond drill bit 8mm for ceramic and glass Kranz KR-92-0002

Diamond drill bit with a diameter of 8 mm is designed for working with porcelain stoneware, ceramics, and glass. It is a tubular drill bit in the form of a hollow cylinder. Used in conjunction with drills or screwdrivers. The cylindrical shank ensures secure fastening of the drill bit in the chuck. The cutting edge is coated with high-hardness industrial diamonds, ensuring precise and clean hole drilling without cracks or chips on the material surface. To prevent overheating during the drilling process, diamond drill bits must be constantly cooled with water. In case of overheating, diamonds easily detach from the base, so drilling must be performed at low speeds.
